ROTARY CUTTER-SLEEVE.

SPECIFICATION forming part of Letters Patent No. 522,262, dated July 3,I894.

To all whom, it may concern.-

Be it known that we, HENRY M. LOOMER, of Hyde Park, in the county ofNorfolk, and CHARLES GRANT BELMER, of Whitman, in the county ofPlymouth, State of Massachusetts,

have invented a new and useful Improvement used in conjunction with arotary cutter that.

is used in molding the edges of boots and shoes; and it consists inenveloping the inserted cutting teeth in a ring that houses in saidteeth so that it may be utilized as arest for the hand of the operatorand also protects the hand from injury resulting from the teeth.

Referring again to said drawings, B represents the sleeve employed inthis invention, which is formed with a passage f extending through it,and which is locked to the shaft by the short stud e. The teeth areshown at a, a and are inserted in shallow slots cut in the periphery ofthe sleeve. Said teeth at their outer edges are flush with band A, andthey have a certain amount of flare as they extend inwardly fromsaid'ring, as shown in Figs. 1 and 3. In using this sleeve the operatorstands as at the right in Fig. 1, or as at the near side in Fig. 3, andthe fingers of the right hand, when manipulating the shoe, bear againstring A; and as said ring extends at the right beyond the ends of teeth aas at cit is not possible that said teeth shall bruise and injure thefingers of the operator in the process of trimming the shoe sole. Thering is curved or depressed in its length, as shown at b, and rounded atd in order that the operator may rest his finger in the depression soformed without danger of injury. By extending ring A over the teeth atthe right and flaring it outwardly at a, trumpet like, as shown in Fig.3, the dust from the cutter is by Application filed January 16, 1894:.Serial No. 497,046. (No model.)

the action of said ring carried directly into the exhaust and does notfill the air to the great discomfort of the operator. And 1n passinground the toe of the sole as also when the cutter is in contact with thesharply curved sole at the shank, said ring formed as shown gives aperfect control to the operator over the action of the cutter at allsuch dlfficult points of the shoe sole. m

' Having thus explained our invention, what we claim as new, and desireto secure by Letters Patent, is- 4 1. A rotary sole cutter consisting of1nner ring B formed to be secured upon the shaft; a series of teeth ainserted in saidring around the periphery thereof, and extending outwardtherefrom, the outer sleeve A secured upon the outer surface of saidteeth and extending inward as at 0 beyond the inner ends of teeth a, toshield the fingers of the operator from injury by said teeth,substantially as spec 1fied.

2. A rotary sole cutter consisting of 1nner ring B, formed to be securedto the shaft, a series of teeth a inserted in said ring around theperiphery thereof and extending outward therefrom, and the outer sleeveA, secured upon thev outer surface of said teeth and formed with alongitudinal depression as at 12 between parts 0 and d, to serve as arest or seat for the finger of the operator when guiding the shoe pastthe cutter, substantially as specified.

3. A rotary sole cutter consisting of inner ring B formed to be securedto the shaft, a series of teeth ainserted in said ring around theperiphery thereof and extending outward therefrom, and the outer sleeveB secured upon the outer surface of said teeth and at its innerend aformed trumpet like or out- Wardly flaring so that the currents of airpassin g between teeth a will by the flaring of sleeve A conduct intothe exhaust the dust cut by said teeth, substantially as specified.
